Personally, I like the decentralized model of energy generation. It bypasses choke points and energy markets that can be manipulated. Since energy is an input for all material goods it can act as a private tax.

However, large industrial facilities have large scale energy needs. Space solar can tap into the suns energy 24-7. With complimentary technologies such as wireless energy transmission, transportation technologies can be freed from dragging along an energy source as a payload. This approach will become essential for space elevators and could revolutionize the commercial aircraft industry.
